And the problem with _that_ is that the world faces any number of problems that absolutely require common solutions.
Yes, international cooperation is hard. Right now nativist groups make it very hard. Perhaps unfortunately it has become necessary. Technological advances of all kinds have ensured that.
Perhaps the reason we have never verified other civilizations is that they get to this point, and destroy themselves or dissolve into chaos. I see no alternative to hoping that we'll "get it right". The ISS represents "one small step" toward that. Even when we are in serious disputes with Russia, they still send our astronauts to the ISS, and we trust them to do that.
Minor point. My church, Unitarian Universalist, is pretty much organized around the idea that _all_ people are worthy, that the goal is a civilization that recognizes that.
It's unlikely any of us will live to see the answer. Perhaps that's fortunate.
Actually, there is some historical evolutionary thought that supports your logic. If we take as a given that evolutionary change is in general a positive process, then for the human race to progress to a point where we can all be cooperative would require an evolutionary "pressure" to force the need. When we look at how and why humans evolved in the first place, the current thinking is it was the evolutionary pressure of apes being forced from a heavily forested environment to a grassland and desert environment. This made bipedalism preferred, necessitated more fine motor skills, etc., etc., all requiring a larger brain. So the upshot may be that if any more advanced civilization interfered with a less advanced one going through the throws of global evolutionary pressures, that they would then doom that species to not being able to advance evolutionary! So in a sense, if our current view of our history is correct, facing global-level challenges and/or forcing ourselves into radically different environments (like colonization and permanent living off-Earth), would force evolutionary adaptations to improve us to deal with those things. The problem with the off-Earth evolutionary pressures is that the evolution will happen to those off-Earth leaving those of us remaining on Earth as distant apes on the plains comparatively. That being the case, best IMO for us to focus on our global problems rather than being swayed by other fancies like space colonization so all of us can become better over evolutionary time. But if those wanting colonization gain control and succeed in that agenda, then for the sake of the human race as a whole we'd have to ensure in that process the continual interbreeding between the colonists and home world folks to try to ensure that the entirety of the human race benefits and not just the off-world component.
Around 10 million years ago, the Earth's climate entered a cooler and drier phase, which led eventually to the Quaternary glaciation beginning some 2.6 million years ago. One consequence of this was that the north African tropical forest began to retreat, being replaced first by open grasslands and eventually by desert (the modern Sahara). As their environment changed from continuous forest to patches of forest separated by expanses of grassland, some primates adapted to a partly or fully ground-dwelling life. Here they were exposed to predators, such as the big cats, from whom they had previously been safe. These environmental pressures caused selection to favor bipedalism: walking on hind legs. This gave the Homininae's eyes greater elevation, the ability to see approaching danger further off, and a more efficient means of locomotion. It also freed the arms from the task of walking and made the hands available for tasks such as gathering food. At some point the bipedal primates developed handedness, giving them the ability to pick up sticks, bones and stones and use them as weapons, or as tools for tasks such as killing smaller animals, cracking nuts, or cutting up carcasses. In other words, these primates developed the use of primitive technology.
